The Mail application may have performance problems after installing Corona 1.0-5

   I told you in the morning that an update for Corona and redsn0w is available, it was released to solve the problems of the iBooks application and also launchd. This update can be implemented either by installing Corona 1.0-5 from Cydia or by restoring the jailbreak with redsn0w 0.9.10 beta 4, but some of those who made the update claim that the Mail application has functionality problems. For some users, the Mail application no longer works properly, more precisely, it does not open or opens and closes by itself, and a possible solution for this problem does not yet exist.

   If you have updated, please leave a comment in which you relate any problems encountered with the Mail application after the update to Corona 1.0-5 or the reuse of redsn0w 0.9.10 beta 4. If you have not yet updated, it would be good to leave it not done until the situation is clarified.
